Or just set up your DNS to forward both x.whatever.net and y.whatever.net forward to the same IP. Note that you can't have an actual IPv4 address forward to a different IPv4 address, unless the server (with the first IP) itself acts as a proxy and redirects incoming traffic to the other server (with the actual IP).

EDIT:
In re-reading your question, it seems that (speculating) you've been running a server on 127.0.0.1 and now want all your users to use the DNS (mc.whatever.net). In this case you'd want anyone connecting to the old IP to be sent to the new DNS. There's no easy way to do this; it's mostly a process of rebranding to ensure that everyone knows the new setup and how to connect to it -- even if you setup something like a proxy to redirect to the new domain, they're not going to notice if it's a seamless transfer, which is what you'd want for people to be able to play who still have the IP stored. The best thing to do is just set your MOTD to the new domain so people are aware of it. Hope that makes sense.

Are you saying that you want to link two servers together? In the form of a cloud server? This is actually pretty simple. You need something called "BungeeCord". This is basically a proxy server, that when connected to via one ip address, it sends you to a default server which you can define within the config. This is NOT a plugin, infact it is it's own separate server. You can also access other servers (defined through the config), by the /server command!

A couple things to note for bungeecord, is that it can only be run on private machines. Meaning your own computer, or a dedicated server/vps. I highly recommend you use a dedicated server or vps because of the fact bungeecord takes up a lot of bandwidth depending on your player traffic.

You would have to have one server running on non-standard port. People would connect to either mc.impactedpvp.net(standard port) or mc.impactedpvp.net:25566 (non-standard port).

If you want two different domain names, eg. mc.impactedpvp.net and mc2.impactedpvp.net, you need to set up a DNS SRV record for the server with non-standard port, e.g., _minecraft._tcp.mc2.impactedpvp.net

Your statements are conflicting. Do you have 2 servers, or do you want 2 IP addresses to connect to the same, single server?

Which of the following do you want? And is the server being hosted on 199.229.253.13 or some other IP address?

Mc.impactedpvp.net ------> server1199.229.253.13 ----------> server2

Mc.impactedpvp.net ---+---> server1199.229.253.13 -------^

So basically, "mc.impactedpvp.net" is my main server, but I also have another server "199.229.253.13", I just want to make it so if they connect to "199.229.253.13" they'll end up on "mc.impactedpvp.net"

So how would I make it so if they connect to 127.0.0.1, they'll connect to mc.impactedpvp.net

If the server is Running on the IP of Server 2, then you can have the domain name of Server 1 (mc.impactedpvp.net) redirect to the IP of Server 2. Then they can join threw either one and still reach the same server.

Look I know how they do it and it's realy logical if you have server 1 running and not server 2 then it will connect to server 1 then you switch it around like server 1 if offline and server 2 is up that is how they do it. Or just make them each have different ports like 1 is 25565 and the other is 25566 or something like that.
